N.B. When the USB/serial communication ca le is connected to the USB interface of a PC that is running (see
su sequent section 1.5), the terminal attery is charged via the PC (max. 500mA); if the terminal is turned
off, all power is used to charge the attery (charge time is however much longer compared to that when using
the a ove mentioned power supply unit provided); if the terminal is running, the system is powered via the
PC and any residual energy is used to charge the attery: in this event, attery charge is maintained and this
is not an actual recharge.
1.1.3 Switching on the terminal
Once the attery is inserted and charged, the terminal can e started up.
To do so, hold the ON/OFF utton pressed for at least 8 seconds until the red LED on the left of the terminal
head does not light up (see figure 1.1.n); consequently, release the ON/OFF utton: the so-called oot-strap
procedure will start and the LED turns orange during oot loader execution, after which the actual operating
system starts up, the display lights up, the 'Nylux' logo appears and the orange LED simultaneously turns off;
after a few seconds the start up procedure is completed.
1.1.4 Reset and turning off the terminal
Press and hold the ON/OFF utton down to turn the terminal off. The display darkens after approximately 4
seconds and the LED on the terminal head turns red: this indicates that the device is resetting:
If at this point the ON/OFF utton is released, the terminal will again perform the entire start-up sequence as
a ove descri ed; on the other hand, y continuing to hold down the ON/OFF utton until the red LED turns
off, the terminal will close down entirely.
